/** |

* MySQL-session environment probe for the staged view-build pipeline. |
| 9 |
* |
| 10 |
* Read-and-warn-only check of operational + DDL-safety MySQL session |
| 11 |
* variables that can silently degrade or break a staged view-build but |
| 12 |
* are not severe enough to halt it. Each out-of-range variable produces |
| 13 |
* one warning-level log line and contributes to a single consolidated |
| 14 |
* deduplicated admin notice (per the task spec: "One concise warning per |
| 15 |
* S1 entry -- no per-stage spam"). |
| 16 |
* |
| 17 |
* Sibling to ABJ_404_Solution_DataAccess_ViewBuildHelpersTrait. Extracted |
| 18 |
* from that trait to keep both files under the project's 1500-line cap. |
| 19 |
* The public probe method probeSessionVariablesAtS1Entry() is the entry |
| 20 |
* point called from runStagedBuildOnce() right after the existing |
| 21 |
* probeSqlModeForBuild() call. |
| 22 |
* |
| 23 |
* Variables covered (P3 + P4 ride-along, see task brief): |
| 24 |
* - innodb_lock_wait_timeout (< 30s) |
| 25 |
* - tmp_table_size + max_heap_table_size (< 16M) |
| 26 |
* - slow_query_log + long_query_time (log on AND threshold very low) |
| 27 |
* - innodb_buffer_pool_size (< 256M) |
| 28 |
* - wait_timeout + interactive_timeout (< 600s; orphan-table cause) |
| 29 |
* - innodb_flush_method (== O_DSYNC) |
| 30 |
* - character_set_server / collation_server (not utf8mb4) |
| 31 |
* - sql_require_primary_key (ON; future CREATE TABLE breaks) |
| 32 |
* - innodb_file_per_table (OFF; tablespace bloat / un-reclaimable DROP) |
| 33 |
* - thread_stack + open_files_limit (very low) |
| 34 |
* - innodb_online_alter_log_max_size (small; S3/S10 ALTER risk) |
